A windows question

[Tonydb]

Hey.

I brought a OEM copy of windows 7 for my current machine (one im on now)

Im going to be building a new one soon , my question is can i move windows over to the new machine?

Or do i have to buy a new one?

ive built a new rig and plan to sell off the parts from the old one..so do I have to sell my mobo with the ssd that has my old windows on it or can I erase the ssd and sell them separately ??
